Determine a suitable dimension for the bridge girder. The bridge girder should meet the following wide$-$ranging requirements: the moment of inertia for your I$-$beam must be higher than the required value, $I_x$ and lower than the maximum allowable value $I_{x-\text{m}\text{a}\text{x}}$ and the width of each I$-$beam should be less than $\frac{1}{5}$ of the value of B given in Table $1.$

use the self$-$weight information given in Table $1$ to calculate the support reaction at each abutment.
